The Portfolio Value vs Benchmark chart is the centrepiece of the Growth page. It plots three lines on a single chart so you can instantly see whether your investment decisions are beating the market.

The Three Lines

  • Invested Amount (purple) — the total cash you’ve put into your portfolio over time
  • Portfolio Value (blue) — what your holdings are actually worth today
  • Benchmark What-If (dashed red) — what your portfolio would be worth if you’d bought the benchmark instead

How the “What-If” Calculation Works

Every time you made a transaction, we simulate what would have happened if that same money had gone into the selected benchmark (e.g., the S&P 500).

For a buy transaction of €1,000 on 15 March 2025:

  1. We look up the S&P 500 closing price in EUR on that date
  2. We calculate how many “benchmark shares” €1,000 would have bought
  3. Those shares accumulate over time

For a sell, we proportionally reduce the simulated benchmark shares. At every month-end, we multiply your accumulated benchmark shares by the current benchmark price. That gives you the dashed red line.

What to Look For

  • Blue line above the red dashed line — you’re outperforming the benchmark. Your stock picks are beating the market.
  • Red dashed line above the blue — the benchmark is doing better. You might consider shifting more into index funds.
  • The gap between the lines is your alpha — shown as a percentage in the summary cards above the chart.

Choosing a Benchmark

Free users compare against the S&P 500. Premium users can choose from 30+ benchmarks including EURO STOXX 50, NASDAQ-100, MSCI World, DAX, FTSE 100, Bitcoin, and popular ETFs like VOO, QQQ, and VWRL.

Tips

  • If your portfolio consists in basically European companies, try comparing against the EURO STOXX 50 instead of the S&P 500 for a fairer comparison.
  • The “All” time range gives you the full picture from your very first transaction.
  • Benchmark data is updated daily after US market close (22:00 UTC).
